PROBLEM TO BE SOLVED: To achieve a high open-circuit voltage in an organic photoactive component that includes a plurality of absorber layers.SOLUTION: A photoactive component including an organic layer comprises single, tandem or multiple cells including two electrodes 2, 9 and a mixed absorber layer which is arranged between the electrodes and includes at least three absorber materials. At least two of the absorber materials are formed as donors or acceptors. One of the two absorber materials is configured as a donor or an acceptor to absorb at greater wavelengths than the other absorber material and has a lower stokes-shift and/or narrower absorption width than the other absorber material.SELECTED DRAWING: Figure 12 |
